Overview

org.apache.solr:solr-core is an open source enterprise search platform built on Apache Lucene

Affected versions of this package are vulnerable to Server-Side Request Forgery (SSRF). The ReplicationHandler (normally registered at /replication under a Solr core) has a masterUrl (also leaderUrl alias) parameter that is used to designate another ReplicationHandler on another Solr core to replicate index data into the local core. These parameters are not checked against a similar configuration it uses for the shards parameter.
